Y Application tiled January 2, 1889. Serial No. 295,264. (No model.)

To all whom, it may concern: B B2 are the shuttle-operating bars.

These guards features constitutingourinvention will be parare so constructed, relatively, that the guard ticularly pointed out in the claims at the end on the shuttle passes under the guard on the of this specilication. shuttle-bar.

Fig. 8 is a sectional Viewl of the thin edge toward the outer end of the corre-v shuttle. used in our invention, showing the sponding one of said shuttle-bars, and so situpin 71,: therein and the spiral spring which ated that it will catch the pin m m2 and by roo 5o holds said pin in position. f means thereof turn the connecting-rod C and A is the shuttle. discharge the shuttle attached thereto just as the end of the other shuttle-bar enters the mouth of the shuttle from the other side. It will be seen later that these blocks are so arranged and geared that the one under the shuttle-bar in possession of the shuttle is always in place to catch the pin on the connecting-rod of that particular shuttle-bar at. the precise moment itis desirable to let off and discharge said shuttle therefrom, and that is at the exact moment the other shuttle-bar is in position and ready to take on and receive the same.

o o2 are the standards holding the said blocks n n2, which standards are held in place by the slotted blocks s s', fastened to the lathe-frame E firmly, the slots in said slotted blocks s s being just large enough to allow the free movement of said standards 0 o2 up and down through the same.

p p2 ale levers, the outer ends of which are applied, respectively, to the lower ends of the standards 0 02. q q2 are correspondinglevers connected, respectively, with the levers p p2 at the points d a. These leverswork upon the pivots c c c2 c2 in the blocks b b h2 b2, respectively, which said .blocks are firmly fastened to the lathe-frame E. It will be readily seen that the connection of these two levers p q or p2 q2 forms a compound lever, and that there is one of these compound levers at each side of t-he loom.

r -r2 Yare wedge-shaped blocks lying immediately under the inner ends of the levers q q2, respectively, and parallel to the sides of the frame of the loom and at right angles to the lathe frame E, the thin edges of said blocks being toward the front of said loom. s2 s2 are the standards to said last-mentioned blocks, said standards being held in position by the slotted blocks t t', fastened firmly to the loom-frame D. The slots in said slotted blocks are just large enough to allow said standards to pass freely up and down through the same.

t 2 are levers attached, respectively, to the standards s2 .s2 at u u" and working on pivots vr o", fastened in the legs of loom-frame D.

u u2 are eccentrics fastened to the ends of the shaft zu in such a way that when olie is turned upward the other will hang downward. The rear ends of the levers t i2 are so placed as to come directly under and close to the eccentrics u u2.

fr is a wheel fastened at or near the center of said shaft u, which shaft is held in position by means of the stays cfv, having sockets in the lower ends thereof to receive the said shaft.

0c is the driving-shaft.

y is a wheel fastened to the driving-shaft at or near the middle thereof and immediately over the band-wheel 2:. Said wheels y and r are connected by means of the chain belt G. \Vheel 1/ should be half as large as wheel r.

e are cranks fastened to the ends of shaft a a2 are pitmen jointed to the cranks z z2 at and to the lathe-frame E.

d d2 are arms fastened to the wheels E E2.

c c2 are rods connecting the outer ends of the shuttle-bars B B2 with the arms d d2.

E E2 are wheels fastened to the cross-bar E of the lathe-frame E.

f is an iron chain belt crossed and connecting the last two mentioned wheels. Any other suitable material than iron may be used for this belt or the chain G. Said chain f is fastened te said wheels at the points 102 and w3.

7c is a wheel fastened to the lathe-frame E by the pivot n', upon which it oscillates.

7L 7L are pulleys fastened to the latheframe E.

g is a chain fastened to the sides of the wheel 7s at the point-s y y and passing over the pulleys h h and around the wheel E and attached thereto by a pin at w', which said wheel E is necessarily a double wheel, while wheel E2 is single, which not only allows E to have two bands, but permits arm d to readily pass arm d2 without interfering with it.

i is an arm fastened to the loom-frame D immediately over the wheel 7e.

l Z are chains fastened to the ends of arm t" and to the sides of the wheel k at 2 .2,1hc object being to regulate the act-ion of the wheel k.

m m are the pivots upon which the latheframe E hangs and moves, which said pivots are placed upon arms attached to and extending from the upper part of the standards of the loom-frame D.

p are thereeds of the lathe.

When our invention or device is put firmly together, and its several parts adjusted and fastened, as herein indicated, and the power applied thereto at the band-wheel F or in any other way or manner which may be preferred, and the manner of which is immaterial to us, as we claim vnothing as to the mode of applying the power, it will be readily seen that the shaft w is turned, the eccentric u2, being downward, presses on the end of the lever t2, whereby the standard 32 is carried upward, taking the wedge-shaped block r2 with it. Now, as the lathe-frame goes back after beating up the cloth, taking with it the lever system thereto attached, the inner end of the lever q2 runs upon said block and is carried upward, whereby the inner end of lever 292 is pressed down, thus raising the outer end thereof and carrying upward the wedgeshaped block n2 until it is so situated that it catches the pin m2 in the end of the connecting-rod in shuttle-bar B2 just as the opposite end carrying the shuttle A comes in contact with the inner end of the shuttle-bar B, advancing from the opposite direction, and at the instant the tenon of said shuttle-bar B enters the mouth of the shuttle the connecting-rod attached to said shuttle-bar B2 is turned, so that the notch (l is loosened from the pin z, thus detaching and discharging IOO ITO

i the shaft w has turned sufficiently the eccentric u2 will be turned upward, letting the block n2 fall down, and by ceasing its pressure on `the pin m allow'the connecting-rodV of the shuttle-bar B2 to resume itsV position, and at the same time the eccentric u at the other end of said shaft will be. turned downward,

and thereby brought to bear on the end oflever t, when the samething will take place on the left side of the loom in regard to the shuttle-bar and shuttle as has already been described as occurring on the right side thereof, and the shuttle will in turn. be played onto the advancing shuttle bar B2. .It can also be readily seen that the guards gg on the shuttle A and the guards f f on the shuttlebars B B2, being pointed, enter between the warp of the cloth as it parts and carry the individual wires thereof over the ends of said shuttle and shuttle-bars and prevent the same frombeing caught and broken by the ends of said shuttle and shuttle-bars, as is often "done in looms where such guards are not used. As the shaft 0c turns, the cranks ,e .z2 revolve with it and cause the pitmen a 0.2 to move back and forward, carrying with them the lathe-frame E, to which they are jointed, as before described. This backward and forward movement of the lathe-frame E not only serves to beat up the cloth by means of the reeds p', but it also causes the wheel lo',

fastened to the side of the said lathe-frame,

to oscilla-te, whereby the chain g', attached to said wheel k, is ymade to move backward and whereby by means of the rods c c2, which connect oneof said .arms withthe shuttlebars aforesaid and the other of said arms with the other of said bars, the said shuttlebars are played backward and forward toward and from each other,`the same being so adjusted as to work in harmony with thelever system hereinbefore described, and also to carry said shuttle-bars together in the center o f said loom and of the cloth therein just at the instant one ofthe blocks a or n2 pressesthe pin m of the connecting-rod of the corresponding shuttle-bar, and turns the connecting-rod cin the shuttle-bar then holding the shuttle, and causes it to give off and discharge said shuttle, which is at the same instant received and taken on by the other Shuttle-bar and carried through the cloth to be again returned and passed in the same way. Ast-he result of the action of the ecrevolutions by centrics u and m2,'ivhereby the action of the lever systems is made alternating, the shuttle is caused to be discharged iirst bythe block a2 and then by the block n on the oppo- Asite side of the loom, which action is facilitated by the fact that the wheel yvis half the l size of the band-wheel o, whence result two bythe Fshaft w.
